BIOS is glitchy after BIOS update from A05 to A20 (Optiplex 3020 SFF)
So after updating the BIOS, it became very glitchy.
With glitching effects, lines on screen, low resolution (lower than than usual) and is overall a mess.
I have an AMD Rx 640 OEM in my system, and the drivers are the latest one. But when I did the update I saw things like Intel something something, so I think the BIOS update also updated the iGPU driver?
Though I do not know for sure.
How do I fix this, and also it still boots to Win10 no problems and there is no lines or glitching there.

The last BIOS update (A20) for your system was released in June 2019. If the update caused performance issues, you may consider downgrade to previous version(s). Along with BIOS firmware, you might have seen update for Intel Management Engine firmware, Intel ME.
